I don't want to be too hard on people who struggle with the idea of God's intervention in the natural order. Miracles are hard to believe in, and they should be. In Matthew 28 we are told that the apostles met the risen Jesus on a mountainside in Galilee. 'When they saw him, they worshipped him; but some doubted' (verse 17). That is a remarkable admission. Here is the author of an early Christian document telling us that some of the founders of Christianity couldn't believe the miracle of the resurrection, even when they were looking straight at him with their eyes and touching him with their hands. There is no other reason for this to be in the account unless it really happened.
The passage shows us several things. It is a warning not to think that only we modern, scientific people have to struggle with the idea of the miraculous, while ancient, more primitive people did not. The apostles responded like any group of modern people--some believed their eyes and some didn't. It is also an encouragement to patience. All the apostles ended up as great leaders in the church, but some had a lot more trouble believing than others.
The most instructive thing about this text is, however, what it says about the purpose of Biblical miracles. They lead not simply to cognitive belief, but to worship, to awe and wonder. Jesus's miracles in particular were never magic tricks, designed only to impress and coerce. You never see him say something like: 'See that tree over there? Watch me make it burst into flames!" Instead, he used miraculous power to heal the sick, feed the hungry, and raise the dead. Why? We modern people think of miracles as the suspension of the natural order, but Jesus meant them to be the restoration of the natural order. The Bible tells us that God did not originally make the world to have disease, hunger, and death in it. Jesus has come to redeem where it is wrong and heal the world where it is broken. His miracles are not just proofs that he has power but also wonderful foretastes of what he is going to do with that power. Jesus's miracles are not just a challenge to our minds, but a promise to our hearts, that the world we all want is coming. -Timothy Keller, The Reason for God, pp.98-99
